What Definition of low cement refractory concrete?
A low cement refractory concrete is termed 'low-cement castable refractory'. It includes castable refractory based on alumina and/or alumino-silicates which contain hydraulic setting cement. The total lime (CaO) content on a calcined basis is between 1 and 2.5 percent. More information is available in ASTM C401.
